Unifocalization of the major aortopulmonary collaterals (MAPCAs) followed by intracardiac repair with ventricular septal defect (VSD) closure and restoration of right ventricle-to-pulmonary artery continuity is the ultimate treatment goal in a case of VSD with pulmonary atresia and MAPCAs. It may be achieved in a single stage or may require multiple surgeries. We present a case of a 2-year-old boy with VSD with pulmonary atresia who underwent single-stage unifocalization of MAPCAs through the midline followed by intracardiac repair using 2 polytetrafluoroethylene tube grafts: one for unifocalization and other as a bicuspid valved right ventricle-to-pulmonary artery conduit.
